**Heat of Combustion Calculation**
In this exercise, you are given the following problem:
"If the heat of combustion for a specific compound is –1120.0 kJ/mol and its molar mass is 98.67 g/mol, how many grams of this compound must you burn to release 872.10 kJ of heat?"
**Calculation Requirements:**
- **Heat of Combustion**: –1120.0 kJ/mol
- **Molar Mass**: 98.67 g/mol
- **Target Energy Release**: 872.10 kJ
**Solution Steps:**
1. **Determine the Number of Moles Needed**:
- Use the equation:
\[
\text{moles} = \frac{\text{Target Energy Release}}{\text{Heat of Combustion}}
\]
2. **Calculate the Mass**:
- Multiply the number of moles by the molar mass to find the mass required.
**Mass Required**:
\[ \text{mass} = \]
